(Cl. i3- 61) 4 Claims. l

This invention relates to an apparatus for collecting liquid sediments and is a furthering of the invention disclosed in my pending U. S. application iiled June 19, 1944, under Serial No. 540,970, this application however providing a more simple and consequently a less expensive structure ci apparatus for sediment testing purposes.

-One oi the objects of the invention therefore is tok provide a hand carried apparatus which is also hand operable.

Another object is to provide the container of the apparatus with a hand operated control valve.

A further object is to combine a double acting control Valve with and as forming a part of a hand carried collecting container.

Still another object is to provide a hand carried container with a Valve, which when coupled with a pressure line, can be operated to both entrain and discharge liquid or fluid into and from the container for testing purposes.

Other objects and advantages will appear as this description progresses and by reference to the drawing in which:

Figure 1 is a vertical sectional elevation taken through this improved apparatus with an intermediate part of the nozzle thereof broken away and showing its relation to a milk can which is shown in dotted lines.

Figure 2 is a side elevation of the apparatus partly shown in section and with the lower end of the nozzle broken away.

Figure 3 is a fragmentary vertical sectional elevation taken approximately on the line 3--3 of Fig. 1.

This improved collecting apparatus is primarily intended for drawing small milk quantities from shipments delivered to dairies from dairy farms or the like for sediment testing of the Vmilk deliveries. Y l

Referring by numerals to the drawing, this improved apparatus comprises a container 4 having a transparent glass or plastic cylinder 5 with an upper head 6 secured thereto by the threads l'I, and the head having a body portion 8 through which a tapered bore 9 is longitudinally disposed at a right angle to the vertical disposition of the cylinder 5.

Leading from the bore 9 is a discharge passageway It! which is formed through an outlet extension II of the body portion 8, and in communication with the passageway I I) is a right angular passagewayV I2 which is also in communication with the bore 9.

Mounted in the bore 9 of the body portion 8 is a tapered valve I3 which is secured inthe bore by the screw I 4 and the co-operating washer I5 at the small end of the valve and secured to the other end of the valve is an operating handle IS.

AThe handle I6 is held in secured position on the valve I 3 by a lock-nut I'I which is mounted on the extension I3 of the valve and secured on the beaded part I9 is one end of a flexible hose or tube 2l! which leads from an air pressure source (not shown).

Formed in the extension I8 and a part of the valve I3 is a longitudinally extending passageway 2! having an angular part 22 which is adapted to communicate with the discharge passageway I0 in the outlet extension II, and formed in said valve beyond or inwardly of the part 22 of the passageway 2l and approximately parallel therewith, and crossing the valve, is a discharge passageway 23, said passageway 23 being adapted to simultaneously communicate at one end with an opening 24 in the cylinder head 6 and at its other end with the passageway I2, in the manner as shown in Fig. 1.

Secured to the cylinder 5 of the container 4 is a pair of bands 25 for the support of the carrying handle 2S and secured to the lower end of the cylinder by screw threads 21 is a body por- I tion 28 in which is formed a downwardly tapering A pocket 3| is formed on the underside of the body portion 28 and which is of a size to form an annular shoulder 32, said shoulder forming a seat for a gasket 33 on the head 34 of a depending nozzle 35 through which milk quantities to be tested for sediments are entrained to the container 4 and subsequently discharged therethrough from the container after collecting the sediments.

The head 34 with its depending nozzle or tube 35 is swingably connected to the head 28 by the hinge 36.'

In the operation of the apparatus for testing and grading milk after its delivery to the dairies in cans or the like from farms, a porous disc 31 is inserted in the seat 38 which is `formed in the head 34, this being done by the operator releasing the head latch 3B, from under engagement with the head 34 of the nozzle 35 and allowing the head and nozzle to swing away from the body portion 28 of the container 4, by the operator inclining 3 the container while holding it by the handle 26.

The container 4 is then swung into a vertical position to allow the head 34 to swing back into the pocket 3| of the body portion 28 of the container and the latch 39 on said body portion is manipulated to under engage the head 34 to secure the gasket 33 against the shoulder 32 of the body'portion 28.

The nozzle 35 `is then engaged in the can 40 and the lower end thereof may rest on the can bottom and the operator then engages the lever I6 of the valve |3 and turns the valve to the position shown in Fig. 1 wherein the angular part 22 of the passageway 2| will communicate with the discharge passageway I in the outlet eX- tension Il on the body portion 8 of the head 6. In this position of the valve, the passageway 23 will be in communication with both the passageway I2 and the opening 24 in the cylinder head 5, and inasmuch as uid pressure is maintained in the flexible tube 20, the `discharge pressure from thetube, through the passageway 2|, its part 22 and` the -discharge passageway Il), a suction will be created in the angular passageway |2, the passageway 23 and-the opening 24 thereby creating a vacuum in the container 4.

The 'suction or vacuum created in the container 4, will cause a portion 4| on each side of the transverse bar 30 of the `disc 3l, to be drawn upwardly from the disc seat 38 in the manner shown in dotted lines in Fig. 1, and a quantity of milk from the'can 40 will be entrained-through the nozzle 35 to the container 4, past the uplifted portions 4| of the porous disc 31.

As the cylinder5 of the container 4'v is of transparent material, the Voperator can readily judge when a sufcient milk quantity has been entrained into the container, and at that instant the operator will actuate the lever I6 to turn the valve -I'3 approximately 180 degrees to dispose the passageway 23 in a cut-oir or out of alinement position with respect to the passageway |2 and the opening 24, to dispose the angular part 22 of the passageway 2| in alinement with said opening 24l to permit air pressure from the hose 2B `to yenter the cylinder 5 against the milk quantitytherein, thus causing the upwardly bent portions 4| of the disc 31 to be forced downwardly against the seat 38, and the entrained milk quantity :in the cylinder will lbe forced through the attened porous disc and returned to the cam 40 through the nozzle 35.

The forcing of the entrained lmilk in the container 4 through the disc 3`| will cause the heavy particles or sediment to be caught and retained by the disc by reason ofits porosity, the sediment loaded disc then being removed from its seat 38 in the head 34 and retained for subsequent inspection by chemists and the like to determine of what the collected sediment or foreign matter consists for an accurate grading of the milk to which the .disc appertains.

Obviously, after returning the entrained milk from the container 4 to the can after collecting sediment therefrom, the valve |3 is manipulated to a cut-olf position with respect to disengaging the passageway 2| from communication with the opening 24 inthe cylinder V5.

Successive like operations of disc insertion on the seat 3'8 of the head 34 for collectingsedment from individual milk shipments may be followed, and in so doing, the operator bycarrying the apparatus in one hand for inserting the nozzle y35 thereof in respective shipments, can readilymove around and among the cans inthe event the 'air 4 pressure tube 20 is of sucient length, while the other hand of the operator can readily actuate the lever I6 for manipulating the valve |3 to the required operating positions to entrain and discharge milk quantities in the manner described.

Having thus described the invention so that those skilled in the art will be able to practice the same, what I desire to secure by Letters Patent is dened in what vis claimed, it being understood that various changes in the device shown and described in detail and not amounting to invention, may be made without departing from the spirit andl scope of my invention.
